What is claimed is: 1. An ingredient delivery device, comprising:a backing member defining an ingredient containing reservoir, said backing member being made of a material which is substantially impermeable to ingredients contained in said reservoir;an ingredient contained in said reservoir comprising an organic solution, wherein said organic solution comprises:a topically active drug agent;an alkylene glycol;a fatty acid ester;a dialkylene glycol alkyl ether; anda polymeric thickening agent;a cover for said reservoir, said cover being made of a material substantially impermeable to ingredients contained in said reservoir, but having at least one opening therein, such that ingredients to be delivered from said reservoir will flow through said opening, but will not readily flow through said material of which said cover is made;said cover being sealed to said backing member at the perimeter of said reservoir by a first seal which is not subject to degradation by any ingredient to be contained in said reservoir;an adhesive layer adhered to said backing member for adhering said device to a patient's skin or mucosa, said adhesive layer not extending to the perimeter of said opening in said cover, such that a portion of said cover surrounding said perimeter of said opening is exposed to thereby define a cover sealing surface; anda unitary release liner covering said sealing surface of said cover and said opening in said cover, said liner being releasably sealed to said sealing surface of said cover by a second seal which is not subject to degradation by any ingredient contained in said reservoir; whereby ingredients contained in said reservoir are sealed therein during storage and non-use by said first and second seals, said cover and liner, but are free to flow through said opening and onto a subject's skin or mucosa when said liner is removed from said device and said device is applied to such skin or mucosa.
